The QCD analysis of xF3 structure function based on the analytic approach
(JINR, 2011)We apply analytic perturbation theory to the QCD analysis of the xF3 structure function data of the CCFR collaboration. We use a different approaches for the leading order Q2 evolution of xF3 structure function and ...2025-05-23 -
Search and identification of effects of extra spatial dimensions in lepton pair production at LHC
(Национальная академия наук Беларуси, 2017)N. Arkani-Hamed, S. Dimopoulous, and G. Dvali have proposed a model (ADD) of low-scale quantum gravity featuring large extra dimensions. In this model, the exchange of Kaluza - Klein towers of gravitons can enhance a ...2025-05-23 -

Analytic approach in QCD and hadronic decays of the tau lepton
(Belarusian State University, 2007)High precise measurements of vector and axial-vector spectral functions in hadronic decays of the lepton stimulate the further theoretical researches of various forms of perturbative expansions and nonperturbative effects. ...2025-05-23 -

Manifestation of Quark-Hadron Duality in e+e− Annihilation into Hadrons
(Belarusian State University, 2014)The Adler D-function which appears in the process of the e+e− annihilation into hadrons is of interest from the point of view of quark-hadron duality, as this function turned out to be a smooth function with no traces of ...2025-05-22 -
Identifying Large Extra Dimensions in Dilepton Production at the Large Hadron Collider
(Belarusian State University, 2014)By considering the present and future LHC energy regimes, we reanalyze the potential of the LHC to discover the effects of large extra dimensions and to discriminate between various theoretical models. We explore the ...2025-05-22 -
On a Physical Relativization of the Strong Interaction within the Relativistic Quasipotential Approach
(Belarusian State University, 2014)New relativistic Coulomb-like threshold resummation S- and L-factors in quantum chromodynamics are obtained. Consideration is performed within the framework of quasipotential approach in quantum field theory formulated in ...2025-05-22 -
Constraints on New Heavy Gauge Bosons from e+e− → W +W −
(Belarusian State University, 2014)We discuss the potential of the International Linear Collider (ILC) to probe Z-Z' mixing and Z' mass by the reaction e+e− → W +W − with longitudinally polarized e+e− beams. We perform here a generic analysis of the deviations ...2025-05-22 -
Z-Z ′ Mixing Effects at the Large Hadron Collider
(Education and Upbringing, 2014)We discuss the expected sensitivity to Z' boson effects in the W ± boson pair production process at the Large Hadron Collider (LHC). The results of a model-dependent analysis of Z' boson effects are presented as constraints ...2025-05-22 -
Pionic Decay of ρ ±–Meson in Relativistic Quantum Mechanics
(Education and Upbringing, 2024)The integral representation of ρ± ⟶ π±π0 decay constant has been obtained in relativistic quantum mechanics based on point form of dynamics. It is shown that soft pion theorem usage in the proposed approach leads to numerical ...2025-05-22 -
Is it Possible to Match Higher-Twist Contributions with Chiral Perturbation Theory?
(Education and Upbringing, 2024)We present a QCD-motivated approach to the analysis of polarized Bjorken sum rule in the nonperturbative infrared region Q2 < 1 GeV2. In this approach, we use the Gerasimov–Drell–Hearn sum rule as a boundary condition and ...2025-05-22 -
Model-Independent Analysis of the Indirect Effects of an Additional Z´ -Boson at CLIC
(Education and Upbringing, 2025)In this paper, we present a technique for analyzing the indirect manifestation of an additional Z'-boson in the planned experiments at future e+e− colliders. The developed technique is based on the representation of the ...2025-05-22 -

Contributions of QED diagrams with vacuum polarization insertions to the lepton anomaly within the Mellin–Barnes representation
(2024)We investigate the radiative QED corrections to the lepton (L = e, µ and τ ) anomalous magnetic moment arising from vacuum polarization diagrams by four closed lepton loops. The method is based on the consecutive application ...2025-05-22 -
